Understanding Port Forwarding

Port forwarding or port mapping involves translating the address (or port number to a new destination),
accepting the packets and forwarding it (using routing table). It's typically used in connecting remote computers
to specific programs running on computer (in a private LAN (Local Area Network)). For example : running a public server (HTTP, port 80)
on a computer in a private LAN or granting SSH access to a specific computer in a private LAN etc.
